The ultimate purpose of emergency management is to save lives, preserve the environment and protect property and the economy. The Emergency management structure comprises four interdependent risk-based functions: prevention/mitigation, preparedness, response and recovery. Mitigation, however, provides a critical foundation for emergency management.
- Prevention/ Mitigation: the aim of which is the elimination or reduction of risk of disasters in order to protect lives, property and the environment
- Preparedness: actions taken prior to an emergency to ensure an effective response including, but not limited to, public education, emergency information, training and exercises
- Response: Actions taken to respond to an emergency or disaster
- Recovery: Actions taken to recover from an emergency or disaster
